correction sequences in n - sum f(r).

[murthy amarnath]

Dear Neil and Seq fans,
, There was a mistake  in my previous mail in writing
the numbers.
30--->30,29 and stop, a(30) = 29. But a(36) = 0 is
correct.
I hope this makes the definition clear.
Just submitted and is not yet included in OEIS.
 
%I A090302
%S A090302 
0,2,3,3,2,5,7,7,3,7,11,11,13,13,5,13,17,17,19,19,11,19,23,23,19,23,17,13,29,29,31,31,23,31,29,0,37,37,29,...
%N A090302 Begin with n and consider numbers obtained
by successively 
subtracting 0,1, 2, 3, ... r in the r'th step. The
largest prime that 
arises in the process.
i.e.  Largest prime of the form n - T(r), where T(r)
is the r'th 
triangular number. 0 if no such number exists.
%C A090302 a(p) = p if p is a prime.
Conjecture:  There are finitely many zeros in this
sequence.
Subsidiary Sequence: Indices of zero.
1,36,...
%F A090302 Largest prime of the form n- r(r+1)/2.
%O A090302 1,2
%A A090302 Amarnath Murthy

Sorry for the error.
